JOHN D. SPRING, OF CLEVELAND, OHIO.
AUTOMATIC SAFE-LOCK.
SPECIFICATION forming part of Letters Patent No. 674,043, dated May 14, 1901. Application filed June 19, 1899. Serial No. 721,027. (No model.)
To ctZZ whom, it may concern:
Be it known that I, JOHN D. SPRING, acitizen of the United States of America, residing at Cleveland, county of Ouyahoga, State of Ohio, have invented certain new and useful lmproven'ients in Automatic Safe-Locks, of which the following is a specification.
The annexed drawings and the following de scription set forth in detail one construction embodying the invention, said detail mechanism constituting but one of various mechanical forms in which the principle of the invention may be used.
In the accompanying drawings, Figure I represents a view of my improved automatic sate-lock secured to the door of a safe, illustrating the levers in their operative and nonoperative positions, the latter position being indicated by dotted lines. Fig. II represents a view with the top plate and levers removed, showing the mechanism in its non-operative position. Fig. III represents a similar view showing the position of the bolt-operating mechanism after the springs have been compressed and before the bolts have been cast. Fig. IV illustrates the position of the parts after the bolts have been cast. Fig. V rep resents a longitudinal cross-sectional view on the line 5 5 of Fig. IV. Fig. VI representsa vertical cross-sectional View on the line 6 6 of Fig. I. Fig. VII represents a view of the bolts in their non-operative position. Figs. VIII and IX represent sectional views of the bolttrip. Fig. X represents a bottom plan view of the safety-detent.
The casing 1, that contains the bolt-operating mechanism, is secured to the safe-door 2 in suitable relation to the locking-bolt 3. A movable locking-frame 4, consisting of the end plates 5 and base-plate 6, is secured in the casing and is preferably movable upon the rods 7 7 and 8 8, that are arranged between one end of the casing and abutments 9, formed integral therewith. A stud 10 projects from the bottom of the frame and engages with one of the locking-bolts. An .opcrating-frame 11, consisting, preferably, of the end plates 12 and bottom plate 13, is mounted within the locking-frame, upon the rods, and is movable thereon. A locking spring or springs 14 are arranged between the operating frame and the locking-frame, preferably between one end of said operatingframe and the opposite end of the lockingframe, and are supported by the rods 7 7. A retracting spring or springs 15, supported by the rods 8 8, are likewise arranged between the operating-frame and the end of the casing.
A plunger 16 is secured to the inner end of the operating-frame and passes through a perforation 17 provided in the locking-frame. The plunger is suitably pivoted at its opposite end to a lip or projection 18, formed upon a rotatable post 19, that is journaled in the casing. Said post projects above the top plate 20, thereby permitting same to be rotated by a crank or other suitable means. An operating-lever 21 is rigidly secured to the rotatable post, above the top plate, and its free end 22 is adapted to engage with a hook or recess 23, formed by the smaller arm of a locking-lever 2 L, that is pivoted to the casing. The longest arm of said locking-lever is preferably provided with a hook 25, adapted to engage with a hook 26, formed on a trip-lever 27, that is likewise pivoted to the casing. Said trip-lever is provided with an upwardlyprojecting arm 28, adapted to engage with and be rotated by an arm actuated by a suitable time mechanism in the usual manner.
The adjacent ends of the lockingbolts are oppositely beveled or cut away, so that same will overlap, and are provided in said beveled portions with recesses 29, formed to receive the opposite ends of a lever 30, that is pivoted between the bolts. A recess 31 is provided in one of said bolts to receive the stud formed on the bottom of the locking-frame. The bolts are suitably guided and held against lateral displacement by means of projections 32, that engage slots 33 provided in the bolts.
Secured to the safe-door, a suitable distance from the casing and arranged transversely of the locking-bolts, is a bracket 34, formed with a barrel 35, that provides a bearing for a plunger 36. A cam-lever 37, provided with an outwardly-projecting arm 38, is pivoted to the top of the stem 39 of the plunger and provides means for moving same againsta coiled spring 40, contained within the barrel. Said plunger is adapted to engage with a recess 41, formed in the bolt, in the bolts non-operative position, and hold same against the pressure of the locking-springs.
In order to cast the bolts, the post is rotated by a crank or other suitable means, which actuates the plunger, and thereby forces the operating-frame forward and compresses both the looking and retracting springs. The operating-lever is raised simul taneously by the rotation of the post and in turn raises the locking-lever, permitting the recess formed by the smaller arm thereof to come into engagement with the free end of the arm. As the locking-lever is raised the hook on its longer arm comes into engagement with the hook on the end of the triplever, whereby the post is held in its rotated position and the springs are held under compression. When the bolt-trip is actuated by closing the door of the safe and causing the door of the safe to engage the cam-lever and depress same, thereby raising the plunger and freeing the locking-bolts, the. locking-springs force the locking-frame forward against the inner end of .the operating-frame or the end of the casing, thereby carrying forward the projecting stud which casts the bolts. Meanwhile the retracting-springs remain under compression. When the levers are released by the rotation of the trip-lever, which disengages same from the locking-lever and frees the operating lever, the retractingspring forces both frames backward into their non-operative position, thereby drawing back the stud on the locking-frame and retracting the bolts.
To prevent the trip-lever from being disengaged accidentally by means of a jar or concussion, a guard 42 is provided, that is pivoted to a lug 43 or to the casing. Said guard is provided with a notch or notches adapted to seat and engage with a projecting pin 44, formed on the trip-lever. Said notches are preferably formed in a slot 45 provided through the guard. A spring 46, secured at one end to the lug or the casing, bears against the bottom of the guard and holds same normally in engagement with the pin. The guard is so arranged in relation to the trip-lever that it is depressed and the pin and notches disengaged by the arm 47, actuated by the time-lock that releases the trip-lever and permits the retraction of the locking-bolts.
To prevent the bolts from being retracted before the levers are released, I provide a detent 48, that is pivoted to the casing, preferably to the bottom of the top plate, and seats in a recess 49, formed in the top of the frames. Said detent is provided with a curved slot 50, adapted to receive a projection 51, that is provided on the bottom of the operating-lever and projects inward through a perforation 52, formed in the top plate, A spring 53 is secured to the detent and passes over said projection, so that when the lever is rotated from its non-operative to its operative position the spring will be brought under tension. The detent is held against upward displacement, however, until the bolt-trip is actuated and the locking-frame is cast by the locking-spring.
The detent is then raised by the spring so that it seats between the abutment formed in the casing and the locking-frame. When the levers are released, the projection, engaging the recess, carries the detent downward on its pivot and permits the retracting-spring to return the frames to their non-operative position.
